Giving Thanks to Stewards Everywhere

Giving Thanks to Stewards Everywhere

Last month I had the immense pleasure of spending time with the Grand Rapids, Michigan Calvin University Plaster Creek Stewards (PCS), a group of faith-based, service-oriented students and educators, dedicated to preserving Plaster Creek (1) , a 27-milelong creek that receives stormwater runoff from the university grounds. In meeting them, and learning about their work, I could not help but note the comparisons of the Chesapeake Bay watershed and the history and work of WSA.

I wanted to share with you the inspiring people and the impactful work they have undertaken to protect their local stream that runs through commercial, residential, agricultural and industrial areas. For context: Plaster Creek drains to the Grand River before reaching Lake Michigan, part of the Great Lakes - St. Lawrence River Basin, the single largest watershed in the world that contains 20% of the world’s supply of surface fresh water.

PCS, as they’re commonly known, formed in 2009, after a group of faculty and staff determined that Plaster Creek was in distress - its water quality was unhealthy for both human and aquatic life, there were high levels of bacteria, and frequent flooding and stormwater pollution were quickly contributing to its demise. Like Maryland rivers, non-point source pollution and agriculture were causing major decline. Also, like Maryland, Michigan is a major agricultural state, its economy relies heavily on farming.

I met with Dr. Matt Heun, an award-winning professor of Engineering and the Director of Sustainability Designation; Dr. Dave Warners, a professor of biology, a restoration ecologist and one of the founders of PCS; Julie Anne Wildschut, an assistant professor of Civil/Environmental Engineering and the project engineer for PCS, and Tom Hartzell, the Environmental Education Coordinator who offers workshops for the local community in an amazing learning space in a LEEDS building that overlooks the university’s Ecosystem Preserve (2) and Native Gardens.

The PCS are all about research, teaching, engagement, and ecological restoration - sound familiar? The conversations they have with residents are the same ones WSA Stewards have with our residents – focused on education, habitat creation, and the role each person plays in protecting our natural resources. Like WSA, the stewards don’t just talk, they lead by example and they take bold action. As I walked the campus, I saw example after example of best-management-practices (bmp), the result of years of dedication and hard work by a team of people on a mission. It reminded me of the hundreds of projects WSA has implemented across our county since its inception. Interestingly, the first class of WSA Stewards graduated in 2009, the same year PCS began its work.

Like AA County Stewards, Plaster Creek Stewards also write grants, provide access to native plants (they have a native nursery on campus), and are innovative and tireless in the work they do to improve their watershed. I encourage you to look at the PCS website to learn more.

As winter’s cold is upon us, and our days grow shorter, it can be hard to stay positive. Like many of you, I find it hopeful and peaceful to visit natural places during these cold months. I find it uplifting to fill my days learning more about native plants and the many stewards who are making plans to plant more in 2026. I encourage you to reach out to others during this time, to make your own planting plans for the New Year and to be grateful and inspired by WSA and the Plaster Creek Stewards for the tremendous work they do to protect our environment.

 

(1) Plaster Creek gets its name from gypsum, a mineral used to make plaster. A plaster mill once stood along the river where gypsum was mined until the early 1900’s

Latin for Gardeners: December End of Year Quiz!

Latin for Gardeners
December’s Native Maryland Plant:
All of them!

Hello Master Watershed Stewards, Naturalists and Gardeners! I hope you enjoyed planting many native plants this year: to manage stormwater runoff, support biodiversity and create a healthier environment for all of us. It’s time to test your knowledge of the botanical names of the plants that were featured in 2025’s ‘Latin for Gardeners’. It’s always best to use the Latin names of plants when you recommend them to friends and the public – there’s only one botanical name for a plant, so it avoids confusion and ensures people select the right plant when shopping at nurseries.

The first group of photos shows the plants in their bloom time with their botanical name listed. The second group shows them in in their winter dress. Do you still recognize them? Can you match the number of each plant in bloom to the letter of them in winter? Good luck, or as they say in Latin, “Fortuna!”

Latin for Gardeners
Novembers’s Native Maryland Plant

Carex pensylvanica Lam.
(KAY-reks pen-sill-VAN-ee-ka)
Common Name: Pennsylvania Sedge

Carex pensylvanica is an upland sedge, semi-evergreen and a groundcover that is often used as a grass substitute in part-shade to full-shade areas. It tolerates moderate foot traffic and once established, it can easily be spread through division.

Ground cover sedges are beneficial for many reasons. They are generally cool-season plants, they emerge in early spring and help to suppress weeds. Some of them, like C. pensylvanica, are water-wise plants; they do well in dry shade, forming an attractive semi-evergreen layer when planted under shade-loving shrubs. Sedges are considered low-maintenance and another great benefit - deer tend to avoid them.

Carex pensylvanica is host to many moths and butterflies. Be sure to allow fallen leaves to stay on any sedges you plant. It will improve the soil, protect overwintering insects, and the plants will have no difficulty emerging in the spring.

October’s Native Maryland Plant

Aralia spinosa L.
(ah-RAY-lee-ah spih-NO-sah)
Common Name: Devil’s Walking Stick, Prickly Elder

Anyone visiting one of the many trails in Maryland’s deciduous forests in late summer and early fall, is certain to see a remarkable plant lighting up the woodland with its massive plumes of flowers – the highly thorny and very tall shrub, Aralia spinosa, commonly known as the Devil’s Walking Stick. Its blooms can be enjoyed from a distance; they appear as clusters of floating clouds and yet, upon closer inspection, they are inflorescence of 5-petaled creamy white flowers, teeming with pollinators, a wondrous sight to behold.

Aralia spinosa is known for its extremely prickly branches and petioles, its bark and roots can cause skin irritation, putting it on the short list of native plants to ‘look at, but don’t touch’. It’s a notable plant in other ways as well - its leaves can reach up to 4’ long, giving it the distinction of having the largest compound (1) leaf in North American temperate forests. As the forest fills in, the occurrence of A. spinosa will decline, it’s shade intolerant so it is most often seen along forest edges.

Although people may want to avoid getting too close to Aralia spinosa, that is not the case for wildlife. This plant has high wildlife value - its flowers and fruit provide food for pollinators, birds and mammals. Deer may browse the leaves, but they aren’t known to favor this plant.

There are plenty of things to scare you in October, don’t let the Devil’s Walking Stick be one of them!

 

(1) Consists of multiple small leaflets that are physically separated from one another, all of them are attached to the same rachis (main axis). Together they create one leaf.
